PACKING.

SPECIFICATION forming part of Letters Patent No. 595,340, dated December14, 1897.

Application filed March 26, 1897. Serial No. 629,310. (No model.)

To @ZZ whom t may concern.-

Beit known that I, CLEMENT J. REsTnIN, a

Athe features named being hereinafter set forth.

Figure l represents a side elevation of a piece of packing embodying myinvention. Fig. 2 represents an end View thereof. Fig. 3 represents themanner of applying the invention.

Similar letters of reference indicate corresponding parts in theiigures.

Referring to the drawings, A and B designate two sections which aretriangular in cross-section and contact at their hypotenuse.

C designates a cushion which rests upon the section A and is inclosed bythe covering D, of iibrous material, preferably braided, said materialalso extending around the outer sides of the sections A and B as a sackor casing.

The cushion C is formed of asbestos, and the sections A and B areformed, say, each of canvas and rubber, the grade of one being differentfrom the other, so that there is a difference in the compactness ordensity of the sections, and as a result when the sections are subjectedto pressure their contiguous surfaces will easily slide or move one onthe other as they are expanded, and there is a regularity of saidmotion, thus avoiding buckling or improper bulging of the sections whenin use, which occurs when each of the sec tions Aand B are made of softor hard material of relatively the same density.

The asbestos provides a iirm cushion, which will be sufficientlyyielding in its nature and does not require the severe pressure of thegland thereon, as is the case with material for cushions heretofore inuse, and, furthermore, the cushion will not burn or crumble Whilesubjected to friction thereon, a feature of great importance in articlesof that class.

I am aware that it is not new to form pack ing of triangular-shapedsections adapted to move on each other, and disclaim the same; but in mycase I make such sections of different densities or compactness, so thatone of them will offer less resistance, permitting the other along itsentire contact-face to move uniformly thereon, so as to prevent anybuckling or wrinkling of the contact-faces.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. yA packing, composed of sections having their contiguous facesladapted to slide on each other, said sections being composed ofmaterials having different densities, whereby buckling and improperbulging of the sections are prevented, in combination with a cushion ofyielding, non-combustible material, said cushion and sections beinginclosed in a casing of fibrous material.

2. A packing consisting of the angular sections A and B, said sectionsbeing composed of materials of different densities, and a cushion ofasbestos located adjacent one of said sections, said cushion andsections being in closed in a casing of fibrous material.
